    06 WRX to make STi power

    I have a 2006 WRX with a full TBE, STi TMIC, and a VF-39; what additional parts would I need to make the power of a stock STi, or maybe a little over.

    Just a tune. I would maybe go with a fuel pump too.

    If you have an 06 or 07 wrx the injectors are larger than the Sti and your fuel pump is fine just get a Cobb and flash the Vf39 map make sure you have an Sti innercooler and your good

    Been running a VF39 setup for over 5 years..... you need:

    An accessport w/ the VF39 map loaded (or a custom tune)
    K&N drop-in filter or SPT intake (as per Cobb Tuning)
    STI Intercooler (or equivilent)
    Necessary Y-pipe (06 WRX Y-pipe will not fit)
    Full TBE (not just a downpipe and stock catback)

    Note.... In order to actually utilize that larger intercooler, you should replace the hoodscoop splitter and bellows (About $100 brand new) with factory STI parts

    Injectors are not needed. 06 "blue" injectors actually flow slightly better than STI injectors of previous years.

    Fuel pump is not "mandatory" either... but a Walbro 255 is always a nice preventative measure.

    The Cobb OTS map, with those exact mods, places the car at 290whp, or 362 engine hp on 93 Octane, whichever you prefer..... 0-60 just under 5, and 1/4 mile times in the high 12s if driven properly.

    Did you have to modify your boost pill?

    That size bit is readily available at any number of places including amazon.com. You'll probably have to buy a 12 pack but on amazon that'll cost you a whole buck. You should also be able to find them at a ton of other places like auto parts stores, Home Depot, etc.

    Yes.... if all you have is the WRX boost pill.

    If you buy a VF39 with the factory STI pill still attached to it.... that is the exact size you need.

    Also... I believe Cobb stocks the correct pill so you don't have to drill.... call them
